If gelatin is made from an unlawful substance, such as pig's meat, bones, skin, or the like, it is unlawful.

Question: "Is gelatin unlawful?"Answer: "If gelatin is made from an unlawful substance, such as pig's meat, bones, skin, or the like, it is unlawful. Allah (Exalted be He) says: {Forbidden to you (for food) are: Al-Maitah (the dead animals - cattle - beast not slaughtered), blood, the flesh of swine} [Surah al-Ma'idah 5:3] Religious scholars unanimously agreed that lard (pig's fat) falls under this prohibition. However, if the gelatin is free from any unlawful substance, there is no harm in using it. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.Permanent Committee for Scholarly Research and Ifta'Shaykh 'Abdul-'Azeez bin BaazShaykh 'Abdul-Razzaq 'AfifyShaykh 'Abdullah GhudayyanShaykh 'Abdullah ibn Qa'udSource: www.alifta.net - Fatwas of the Permanent Committee>Group 1>Volume 22: Hudud>Slaughtering and Hunting>Foods>Ruling on gelatin
